Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the main defect of the prior art is that each scheme in the prior art mainly relies on the positioning information of the user's GPS (Global Positioning System, Global Positioning System) and Wi-Fi near the point of interest. -Fi information, etc., the data source is relatively single, so there will be problems of poor coverage to varying degrees

[0098] Figure 3a It is a flowchart of a method for establishing a user visit prediction model according to the third embodiment of the present invention. This embodiment is optimized based on the above embodiments. In this embodiment, it also preferably includes: obtaining the last search time in the training samples; calculating the difference between the last search time and the user's actual arrival at the search location. The difference between times is used as a training target value; the set regression model is trained using the last search time and the training target value, and the trained regression model is used as a visit time prediction model. Correspondingly, the method in this embodiment specifically includes:

[0099] 310. Generate candidate samples according to the user's map search data.

[0100] 320. According to the positioning track data of the user, select a candidate sample that satisfies the actual visit condition of the user as a training sample.

Abstract

Embodiments of the present invention disclose a user visiting prediction model establishment and user visiting prediction method and apparatus. The user visiting prediction model establishment method comprises generating candidate samples according to map search data of a user; selecting the candidate sample satisfying an actual visiting condition of the user as a training sample according to positioning track data of the user; determining training characteristics corresponding to the training sample according to arrival mode associated information in the training sample; and training a set single-class classification training model by using the training characteristics corresponding to the training sample, and using the trained single-class classification training model as a user visiting prediction model. According to the technical scheme, the technical problems that for existing methods for calculating and deducing user visiting POI, due to the fact that the map search data are not considered, the data are single, and using coverage is poor to various degrees can be solved, an existing user visiting prediction technology can be optimized, and accuracy of user visiting prediction can be increased.

Description

technical field [0001] The embodiments of the present invention relate to information processing technology, and in particular to a user visit prediction model establishment and visit prediction method and device. Background technique [0002] With the continuous development of mobile Internet and mobile smart devices and terminals, terminal users generate a large amount of offline data such as positioning and trajectory. Offline data truly reflects the behavior characteristics of users in physical time and space, forms a good supplement to online data, improves the calculation of user portrait attributes, and is widely used in many specific applications such as online information push and precision marketing. In particular, if it can be determined or predicted that the user has visited a POI (Point Of Interest), such as a hotel, restaurant, etc., then information push that accurately hits the actual needs of the user can be completed. [0003] At present, there are roughly...
